The cameras on most smart phones tend to be rather simple affairs so it's not surprising that savvy inventors have dreamed up numerous add-on attachments such as mini-microscopes and wide/telephoto adapters. They do tend to be rather elaborate and brand-specific, however, not to mention somewhat pricey. Not this one though - the Macro Cell Lens Band is a simple close-up photography solution that has two definite pluses - it works on any camera equipped phone and it's very inexpensive.
